This paper focused on health costs, particularly their increase, from a management approach. This implied to underline those aspects associated with the resources used and the effectiveness of results for the health of individuals and populations. Five possible causes that might explain the multi-causality of the health cost increases were presented. Three of them had not been deeply analyzed in the studies on health costs and had a basic management component: corruption, poor organization of service and irresponsible management of resources on the part of providers. The analysis of the last mentioned cause is extensive since it has a greater management interest, accounts for a high percentage of costs and it is at the same time an element that can be changed at the primary and secondary care levels by the managers. In order to extend the analytical possibilities, the cause was seen as a problem to which Ishikawa´s cause/ effect diagram was applied. This allowed disclosing the subcauses upon which the managers might work to turn irresponsibility into co- responsibility. The last part of the paper analyzed each of these subcauses and made recommendations about the useful management methods, abilities and technologies to bring about the desired changes.
